Our Story

Read More

The Operative Plasterers' and Cement Masons' International Association (OPCMIA) of the United States and Canada is a labor union that represents plasterers and cement masons in the construction industry in North America.

As the oldest Building and Construction Trades Union in the United States, the organization traces its roots back to 1864, during the American Civil War, when an organization known variously as the National Plasterer's Union or the National Plasterers Organization began to unify the various local craft unions that represented workers in the trade.

Why Join?

First and foremost, the Union belongs to its members. We have a say in how our organization operates. We elect our own leaders from within our ranks, so our representatives understand our trade and the issues that matter to us because they have done our jobs. 

As a union member you will have the protection of a union contract with basic rights including: 

  • Improved job conditions. 
  • The right to a fair hearing. 
  • The ability to speak out for yourself and your fellow workers on work-related issues.

We collectively bargain our own contracts. Our representatives are committed to negotiating better wages, benefits and conditions for their members. Through bargaining, we negotiate benefits such as:

  • Health and welfare to protect you and your family when you’re sick or injured.
  • Dental and vision care benefits.
  • Pension benefits to help you live the quality of life you deserve upon retirement.
  • Normal working hours, shift work, travel pay and overtime, etc.

We bargain for safer job conditions and enhanced health and safety programs that can help you prevent on-the-job injuries and better equip you for today’s market.
